In Chinese medicine, doctors often look at a patient’s tongue to make a diagnosis about their internal organs. This is referred to as a “tongue diagnosis” or “to make an examination by taste.” A normal tongue, called Quan, has an even coating. However, if one part of the tongue is thicker, it is called Pian. By using Quan and Pian, a doctor can tell which internal organs are ailing. The parts on tongue that reflect the five internal organs are: Tip of tongue reflects heart (sensitive to sour taste) Sides of tongue reflect liver and gall bladder (sensitive to bitter taste) Center of tongue reflect lung and stomach (sensitive to astringent taste) Root of tongue reflects kidney (sensitive to fishy taste) Therefore, when drinking concentrated Maxmyer NanoCalcium, the taste may differ depending on the conditions of their internal organs.
